Not a big fan of Sense, but I can confirm (or add my confirmation) that the Sense 3 lock in WL works like it does in Sense 3 (I had a Sense 3 phone for 6 days).
The latest WL doesn't fix the stock lock coming up after it, and sometimes WL has to be unlocked twice. I'm not sure what's up with that, but it's a buggy app for sure. I don't blame TeslaCoil Software, though. They do good work. It's Google's fault there isn't a clear way to remove the lock screen or otherwise change it. Only hacks.
